And what do we find, tucked away on page 526, but a little insight into the mind of Ed Miliband - written, of course, before he ever became party leader - on Labour's 2010 manifesto, which he wrote:
"It adopted radical rhetoric, but when it was boiled down it was vague and appeared to avoid any hard choices."
Critically, the observation is not to do with Ed's politics, but his way of operating. Now, to be fair, since about June of this year, Ed has shown a much greater appetite for hard choices or, at least, risk-taking, as I acknowledged in my penultimate post, and others. But this nugget shows where his default behaviour had been coming from a mere year before, in early 2010.
We need to hope that this change is permanent and the result of an ongoing learning process, as it was for Blair, rather than merely a blip in an inherent and inescapable personality trait. Brown, let us not forget, was famously risk-averse, and it ultimately hurt him. But people can change, and politics is a game which rewards adaptability.
